Upgrade questions..

[QuantumMechanic]

We are in the midst of upgrading from 3.4.8 to 3.10.2 -- Yes, it has been a while.  We have run into a couple of questions.


The signature for UICamera Raycast has changed from:

1.         static public bool Raycast (Vector3 inPos, out RaycastHit hit)
2.  

To:

1.         /// <summary>
2.         /// Returns the object under the specified position.
3.         /// </summary>
4.  
5.         static public bool Raycast (Vector3 inPos)
6.  

How do I determine what object the raycast hit?


UIPanel's no longer has a hard clipping option.  What's the correct way to accomplish a hard clip with texture clipping?


Is there a new equivalent to the formerly available UIPanel.onChange?

Seems like there are a lot of nice new features to play with.  Any hidden gotchas for folks who have not upgraded for a while?

UICamera.lastHit stores it.

What did you use onChange for? In the current dev build of NGUI I actually added UIPanel.onCreateDrawCall because I needed access to the draw call's game object in order to add LOD to it.
